BRIEF DESCRIPTION OF ACCIDENT
An employee was installing a small diameter pipe in a trench 3 feet wide, 12-15 feet deep and 90 feet long. The trench was not shored or sloped nor was there a box or shield to protect the employee. Further, there was evidence of a previous cave-in. The employee apparently recentered the trench, and a second cave-in occurred, burying him. He was found face down m the bottom of the trench.
